Roltamax's Inline Transmission Test Dynamometer is specialized equipment that measures torque and speed directly in a vehicle's drivetrain, installed inline between the engine and wheels (or output) to test the transmission's performance, efficiency, and durability under simulated driving conditions without absorbing power like other dynos, helping diagnose issues in gears, clutches, and hydraulics for automotive, heavy-duty, or even military applications
How it Works
In-Line Installation: It's placed directly in the power path, often between the transmission output and the driveshaft or axles.
Torque & Speed Measurement: It uses sensors to capture the rotational speed (RPM) and torque being transmitted through the shaft.
Power Calculation: Power is calculated from these measurements (Power = Torque x Speed).
Simulated Loads: It applies controlled loads (often with eddy current absorbers) to mimic different driving scenarios (acceleration, cruising, shifting).
Performance Testing: Verifies power delivery, gear shifts, and efficiency.
Diagnostics: Identifies issues like slipping clutches, hydraulic problems, or binding gears.
Remanufacturing Validation: Ensures rebuilt transmissions meet specifications.
Versatility: Can test inline, V-drive, and angle-drive transmissions for various vehicles (cars, buses, military).
Types of Load Units
Eddy Current Absorbers: Common for creating controlled loads, often used with AC motors.
AC/DC Motors: Can act as motors (to drive the transmission) or generators (to absorb power).
